Hi Adrian,

The plan is to use grouptaskqueue in the end. From what I can see all 
the pieces are in place for that. Then the tasklets will run on the same 
CPU that they were scheduled on.

Some patches needs to go into the grouptaskqueue first:

1) grouptaskqueue needs to support LinuxKPI module unload. There is 
current missing/unimplemented drain logic in grouptaskqueue APIs.

2) Needs to expose internal gtaskqueues, so that we don't create 
unneccesary threads to handle a single IRQ, which is the case currently.

I've already CC'ed a few people on this, but not action yet. If you can 
help, would be great.

BTW:
TASKQGROUP_DECLARE(net);

in sys/gtaskqueue.h seems non-existing and should be removed.
